Specification of Letters Patent. Patented Dec. 16, 1919.

Application filed April 11, 1919 -Sria1 No. 289,359.

To all whom it may concern:

Be it known that I, WILEY W. CoNwAY, a citizen of the United States, resid ng at Huron, in the county of Yavapai and State of Arizona, have invented new and useful Improvements in Cotton-Gins, of which the following is a specification.

This invention relates to cotton gins and particularly to what is known as roller cotton gins, the broad object of the invention being to produce a practical rollergin which will gin long staple Egyptian cotton asjwell as the ordinary common short staple cotton, the machine efi'e'ctively separating the seed from the fiber without breaking orcutting or damaging the fiber, thereby greatly 1ncreasing the value of the staple in quality as well as price.

Viith the above andother objects in view the invention consists in the novel construction, combination and arrangement herein fully described, illustrated and claimed.

In the accompanying drawing Figure 1 is'a plan view of the machine.

Fig. 2 is an end elevation of the same.

Fig. 3 is a vertical transverse section through the machine.

Fig. 4 is a vertical longitudinal section through the same.

The improved machine comprises in a simple and preferred embodiment thereof, a pair of ginning rolls 1 arranged in the same horizontal plane and in spaced relation to each other as shown in the drawings. The ginning rolls 1 are covered or faced with rubber 2 or similar material for obtaining the necessary grip upon the fiber of the cotton as will appear.

The ginning rolls 1 are driven simultaneously in opposite directions, the upper portions of the rolls moving inwardly toward each other. Arranged between the upper portions of the ginning rolls 1 is a trough designated generally as A and comprising a grate like bottom 2 and upwardly and outwardly diverging and curving aprons 3, the same being curved to conform to the peripheries of the ginning rolls 1 and extending substantially one quarter around the oircumference of said ginning rolls. The grate 2 is formed of parallel longitudinal bars 4 and transverse grate bars 5 connecting the bars 4 and arranged in spaced relation to each other and at such distance apart as to permit the cotton seed to pass between the same giter the seed have been separated from the er. a

The aprons 3 comprise arcuate bars 6, the same being formed with bearing openings 7 for a series of parallel separating or retaining rolls 8, the latter being-arranged in parallel and spaced relation to each other and working in contact with the ginnin rolls 1, motion being thus transmitted to t ese retaining rollers 8.

Arranged within the trough A and just above the grate 2 is a spiked roller 9 driven in any suitable manner and serving to agitate and move the cotton within the trough until the fiber thereof is enga'ed between the rollers 8 and the ginning rol s 1.

Arranged beneath the grate 2 is a conveyer trough 10 in which is a rotary spiral conveyor or auger like conductor 11. The seed falling through the grate 2 are received in the conveyor casing S and are conducted outwardly toward and from one end of the machine by means of the conveyer 11.-

Arra'nged underthe conveyer 11 and also beneath the ginning rolls 1 is a doffer roll 12 having brushes or bristles 13 on the periphery thereof. Motion is imparted to the dofler roll 12 in any suitable way, said roll being mounted within a casing 1a communicating with which casing 14 is a lint flue 15 for carrying off the lint from the machine.

The seed cotton is fed into the machine by means of any suitable hopper which dischar 'es the seed cotton into the trough hereinabove described and as shown in the drawings in which trough the fibers are seized and engaged by the rollers 8 and between said rollers 8 and ginning rolls 1, the result being that the fiber without being broken, out or injured is drawn from the seed, the latter being left at the inner sides of the roller 8 and falling upon and through the grate 2 and into the trough 10 after which they are conveyed outwardly. and discharged at one end of the machine by means of the conveyor 11. The fiber is carried downwardly into the casing 12 and all lint brushed and discharged therefrom, the fiber being carried from the machine in any suitable way or by any suitable means The result is that the full length of the fiber is preserved, thereby adding materially to the value of the fiber both as regards commercial value and price.

The mechanism for driving the several rotating parts of the machine are illustrated in Fig. 2. The rollers 1 have fast thereon intermeshing gears 15 so that said rollers operate equally in opposite directions. The shaft of one of the rollers 1 has fast thereon a sprocket wheel 16 from which a chain 17 passes around a smaller sprocket wheel 19 on the shaft of the conveyor 11. A large gear 18 is fast on the. other roller shaft and is geared to a small pinion 20 on the shaft of the brush or doffer roll 12. Springs 21. are connected to the frame of the machine and to the members 6 for holding the rollers 8 against the rolls 1. rollers 8 to obtain the necessary grip on the fiber to effect a separation between the fiber or cotton and seed. The gears illustrated in Fig. 2 are proportioned so as to give the proper rotative speed to the several parts referred to.

I claim 1. A cotton gin, comprising a pair of ginning rolls, means for rotating said rolls in opposite directions, a trough arranged be tween said rolls, and having a grate at the bottom thereof, and relatively, small retaining rollers in spaced relation to each other journaled in said trough and bearing against the first named rollers.

2. A cotton gin, comprising a rotary ginning roll, a series of parallel seed retaining rolls bearing against and rotated by said ginning roll and arranged in spaced relation to each other, and a seed trough ar- This enables saidranged to receive the seed after being sep arated from the fiber by said retaining rolls.

3. A cotton gin, comprising a pair of oppositely rotatlng ginning rolls, a seed trough between said rolls having a grate, and parallel seed retaining rollers in spaced relation to each other working in driving contact with said ginning rollers.

4. A cotton gin, comprising a pair of oppositely rotating ginning rolls, a seed trough between said rolls having a grate, and parallel seed retaining rollers in spaced relation to each other, working in drivin contact with said ginning rollers, and a seed conveyer beneath said grate.

5. A cotton gin comprising a pair oi oppositely rotating ginning rolls, a seed trough between said rolls having a grate, and parallel seed retaining rollers in spaced relation to each other, working in driving contact with said ginning rollers, and a seed conveyer beneath said grate, and a doiier roll beneath said ginning rolls.

6. A cotton gin, comprising a pair of oppositely rotating ginning rolls, a seed trough between said rolls having a grate, and parallel seed retaining rollers in spaced relation to each other working in driving contact with said ginning rollers, and a spiral roll rotating within said trough and between oppositely arranged retaining rollers.

In testimony whereof I aiiix my signature.
